Title: Sheet orienting apparatus
IPC: B65H9/10
Filed: 1974-11-07
Abstract: 1459572 Registering sheets PITNEY-BOWES Inc 7 Nov 1974 [8 Nov 1973] 48260/74 Heading B8R A sheet, e.g. fed by rollers from an electrostatic copying machine, is laterally and longitudinally registered, with respect to feed direction, on a support plate 12 whilst being held substantially flat thereon by overhead wire guide fingers before being fed on by grippers (22), (24), Fig 2 (not shown), e.g. to a lithographic printing press. When a photoelectric cell 183 senses the front edge of a sheet on the support plate 12, a motor 104 is energized to rotate a cam shaft 102. The cams on this shaft cause, via followers and suitable linkage, the following sequential operations: clockwise rotation of a shaft 128 and consequential lowering of normally raised rear guide fingers 124 thereby holding the sheet flat; (2) inward movement of a longitudinally extending side registering plate 30 towards a fixed counter plate 33, causing the sheet therebetween to buckle longitudinally, and subsequent outward movement of plate 30 so that it is spaced from the counterplate a distance equal to the width of the sheet; (3) longitudinal movement of the fingers 156 of a rear registering device, the fingers protruding from slots 158 in the support plate and urging the front edge of the sheet against stops (25) provided on the grippers (22), (24); and (4) clockwise rotation of a shaft 122 and consequential raising of normally lowered front guide fingers 120 which hold the sheet flat. The grippers are controlled by the operation of the printing press, and operate in timed relationship with the registering means to feed the sheet to grippers provided on the master cylinder of the press. A vacuum drying device may be located above the support plate.

Title: Four stroke internal combustion engine
IPC: F02B33/26
Filed: 1975-01-27
Abstract: 1504279 Charging IC engines; lubricating pistons H LITZ 27 Jan 1975 48406/74 Heading F1B [Also in Division F2] A four-stroke I.C. engine comprises a cylinder 31 with a combustion chamber 34 having intake and exhaust valves 15, 43; a crank-case 50 enclosing a crank-case chamber of generally cylindrical shape, the crank-case and cylinder forming a compression chamber for compressing air, or air fuel mixture for use in the combustion chamber; a crank-shaft 51 in the crank-case 50 having an exterior surface contour which substantially matches the interior surface contour of the crank-case; a piston 30 slidable in the cylinder to cause above atmospheric pressure in the compression chamber on its down stroke and below atmospheric pressure therein on its up stroke. A conduit which may be a holding chamber 16a communicates with the combustion chamber intake valve 15 and the crank-case chamber via a one-way valve 40, the crank-case chamber also communi-  cating via a one-way valve 4 with a source of air or mixture, the valve 4 opening automatically when the compression chamber pressure is below atmospheric pressure and the valve 40 opening automatically when the compression chamber pressure is above the holding chamber pressure. The piston is lubricated by carrying oil from a source via a lift tube 20 associated with the connecting rod 19 linking piston 30 and crank-shaft 51. Oil passes via port 22, Fig. 7, non-return valve 22a and tube 20 with riffles 21 to port 24 leading to channel 13a in wrist pin 14 on which the piston is mounted, the oil then passing via passageways 11 to the periphery of the piston 30. The riffles 21 splash oil upwards during operation of the engine. The oil is carried to the port 22 through crank-shaft 51 and along connecting rod bearing 17. Alternatively the piston may be lubricated via oil holes 2 in its periphery or oil may be added to the charge entering the compression chamber to lubricate the interior walls of the cylinder 31 and the wrist pin 14. The crank-shaft 51 is balanced by having holes (not shown), bored therein, which are sealed or filled with lightweight material so as not to increase the volume of the crank-case chamber.

Abstract: 1,059,379. Gaseous discharge tubes. GENERAL ELECTRIC CO. Dec. 12, 1963 [Jan. 7, 1963], No. 49185/63. Heading HID. In a gas discharge tube comprising a thermionic cathode 7 surrounded by a heat shield 6, a refractory metal cold cathode 25 is provided within the heat shield and in the discharge path to supply a part of the anode current during fault current operation which might otherwise damage the thermionic cathode. As shown, the cold cathode comprises a pair of arcing horns 27 connected to the cathode supply leads 11, the directly-heated cathode 7 comprising a metal mesh 19 spirally wound about an insulating sleeve 20 and impregnated with a sintered alkaline earth metal oxide.

A bell-shaped graphite anode, Fig. 1 (not shown), surrounds the discharge aperture 9 in shield 6, the anode and cathode structure being supported from leads extending through opposite ends of the tube envelope, and the tube contains mercury vapour and/or an inert gas. During normal operation, oxide evaporated from the thermionic cathode is deposited on the W, Mo, Ta or Ni arcing horns 27 and forms an insulative coating which collects ions from the plasma within heat shield 6 and provides voltage gradients for establishment of cathode spots on the arcing horns during fault current operation.

Abstract: 1370040 Regulating I C engine fuel injection AMBAC INDUSTRIES Inc 25 Oct 1972 49190/72 Heading F1B A device, positioning the maximum fuel stop 34 for a centrifugal governor 10 controlling the fuel control rod 26 of a turbo-charged diesel engine injection pump 14, comprises a cylinder 48 containing a piston 60 subject on one end surface 88 through a passage 78 to engine pressurized fluid, e.g. lubricating oil, and biased by a spring 64 against the fluid pressure. A piston 98 is slidable in a bore 70 in the piston 60 and is subject to intake manifold pressure through passage 126 in the cylinder 48. A spring 118 biases the piston 98 against the manifold pressure and the piston rod 102 is connected to the stop 34. In operation, the piston 60 is biased by the spring 64 against a sealing ring 82 to a position permitting increased fuel for starting until the pressurized fluid acting through the passage 78 reaches a predetermined pressure at which the piston is moved against the bias of the spring 64 to abut the other end of the cylinder, the pressure then acting on the complete end surface 88. During engine operation other than acceleration and low speed full load operation the intake manifold pressure is above the predetermined value necessary to move the piston 98 against the bias of the spring 118 and the stop 34 is positioned to provide a normal running maximum supply. Below the predetermined manifold pressure the piston 98 moves against the spring bias and the maximum fuel supply is limited.

The valve 23 comprises a plate 25 urged by the pressure in the pipe 22 to a position closing a discharge pipe 29. When the pressure drops in the line 14, 22 due to the piston cutting off pressurization from the space 3, a spring 26 moves the plate 25 away from the discharge pipe 29 to connect the line 22 to the pipe 29 and thereby further reduce pressure in the pipe 14, 22. The lowering of the pressure due to the valve 23 speeds up changeover of the distributing valve 10.

Title: Frequency-shift modulator

Filed: 1963-12-30
Abstract: 1,063,490. Data transmission; twinplex systems; transistor multivibrator circuits. WESTERN ELECTRIC CO. Inc. Dec. 30, 1963 [Jan. 23, 1963], No. 51135/63. Headings H3T, H4L and H4P. A frequency-shift modulator comprises a transistor multivibrator having cross-coupled stages in which the cross couplings each include a pair of resistors 19, 20 or 27, 28 and a diode 22 or 26. By biasing the diodes by binary data one resistor of each pair is either in parallel with or isolated from the other. Thus the data switches the multi-vibrator between one discharge rate and another, i.e. between one frequency and another. The modulator can be modified for multiple operation by providing a similar resistancediode combination for each data source, so that there will be a discrete frequency representing each possible simultaneous combination of inputs. To obviate the possibility of the unit resting in one state permanently on switching on, capacitor 38 is arranged to be charged, if transistor 14 is saturated for a sufficiently long period, to a level at which transistor 17 conducts, thereby grounding the bases of 14 and 15 so that 14 is cut off and the unit starts to oscillate.
